Per Acre = A fixed pasture lease rate for the entire grazing season based on the projected forage conditions.
Per lb Gain = A fixed lease rate based on the added weight the livestock gain while they are on pasture. This approach is best suited for stocker cattle rather than beef cows.
Per Head = A fixed lease rate for entire grazing season that will vary for different types of livestock. For example, lower rates are usually charged for stocker cattle and higher rates for cows.
Per AUM = A fixed per animal per month lease rate provides flexibility in allowing for different types of livestock. An AUM is defined as the amount of forage required by a 1000 pound cow for one month. A pasture rated at 1000 AUM's could support 1000 cows for one month or 200 cows for five months. You need to consider your average forage quantity and length of grazing season when calculating your per AUM minimum lease rate.X
